I'd have expected that to work, because syntactically the slice is
assigned to only after the new, smaller slice is fully constructed --
including all the data copying. But it still make me twitchy about
the possibility that the runtime shortens the slice before reading all
the data, resulting in

Hi,
I get DNS lookup timeouts many times a day when running Go HTTP clients on
Kubernetes, where UDP packets are sometimes dropped due to a race condition
in the Linux kernel. I'd like to propose a small standard library change to
help debug these scenarios and get some feedback on the idea
As Michael Jones said, you still need to play by the testing package's
benchmark rules for it to be able to benchmark your code.
So something along these lines.
func BenchmarkMarshalSample(b *testing.B) {
for i:=0; i < b.N; i++ {
var sum int64
// start := time.Now()
I know this is an old thread, but I found it, so others might, too.
I struggled with a similar problem of the Go HTTP client not sending client
certs when challenged by the server. Yet, curl worked fine when given the
same client certs, calling the same server endpoint. The cert chains I

I think that question is more about how to copy fields from one struct
to another. For example one struct contains some tags (for example to
work with some db orm), and proto struct don't have such

OK, I got it. You were trying to change the code I was benchmarking, and I
did not realize you were trying to say a benchmark must have the ability to
run b.N times.
Yes, that was the problem. This fixed it:
func BenchmarkMarshalSample(b *testing.B) {
var sum int64
for i:= 0; i <
OK, I added a sum of the rand to the demo code and the results are the
same. Since it is displaying the sum, it seems clear that the code is not
optimized away.
Again, I am NOT trying to time each iteration of the loop. This is a
minimal demonstration of a weirdness I was seeing in my own
as was explained, the loop needs to be "for i:=0; i < b.N; i++"
as was mentioned, the compiler's dead code elimination efforts can
frustrate benchmarking. they way to make sure the test code survives is to
not let it be dead code. for example
// external var dummy
func
for i:=0; i < b.N; i++ {

I understand. This is a simulation of a single bigger task that takes a
while. I'm not trying to time the rand function inside the loop. The loop
is simply to burn time. This simple function is a minimal example that
Hi,
I am using go-1.14.1. I am using this code to remove i-th element from the
slice.
s = append(s[:i], s[i+1:]...)
It works on my machine but gives panic on docker-container with error
"range out of bound" when it has just 1 element left.
I want to check if this is an unsafe code and how
You are supposed to run the loop b.N times, not
some fixed constant. Also make sure the compiler
doesn't optimize away the whole function.

Hi Folks,
I'm getting weird results from Benchmark. Maybe someone can help me
understand this. I'm running on amd-64 (Threadripper 16 core 32 thread)
Windows 10. Go 1.14.3
I have the benchmark below (main_test.go) on a minimum "hello world"
main.go (just like playground).

How to generate the cfg of the following Replace method ? I used this
command "GOSSAFUNC=Replace:* go tool compile main.go" but it doesn't work.
Thanks.
package main
type byteReplacer [256]byte
func (r *byteReplacer) Replace(s string) string {
var buf []byte // lazily allocated
19 matches
